Interaction parameters for DME with water and hydrocarbons

[mahesh009]

Hi All,

I couldn't find binary interaction parameters for DME with water and other hydrocarbons in simulators such as HYSYS,PRO/II and Aspen plus.How can i get those parameters?
My process is to separate DME from mixture of hydrocarbons(c3-c9) and water. My objective is to recycle DME from the effluents of MTBE and TAME unit in the refinery process. Appreciate your help guys..
